I really liked this provider he was very nice and did well with my son who's only 2

July 19, 2020 11:43 PM

Doctor was late about an hour, then when reaches you does not spend enough time with you. Also, the helpers will ask you to leave before you are done. You might be waiting for the doctor to return so that you can ask more questions and they will tell you that he was finished with you.{ This is unsatisfactory} to patients. We are aware that he has to see other patients but maybe if he wasnt late all of the time it wouldnt be soo bad. I believe that they need to schedule his patients as appropiate to him or his schedule as possible.

Generally he cares about his patients.

May 12, 2020 11:47 AM

My previous physician closed her practice and I was in need of a new physician. Dr. Imlach is my husband s physician and both my sons when they lived here and had always given excellent care to them, so I requested him to accept me as well, and he was kind enough to do so and very quickly. I was without a physician in the middle of a pandemic and had no way of renewing my thyroid medication, and he took care of my needs quickly.

May 12, 2020 11:47 AM

it was my first video visit and went extremely well, thanks to Dr. Imlach and his nurse.

May 7, 2020 9:31 AM

Dr. Imlach is a great Dr. I trust his knowledge and experience. My Dad was a patient at another hospital under the Presence medical group, and I transferred him to advocate medical group. And now he has the same primary care Dr. that I have . ( Dr Imlach ) and also my Husband . My husband and my 92 year old dad , both have very serious medical conditions. We are very satisfied with Dr. Imlach. He will ease your concerns and have you feeling better soon.

My visit with Dr. Imlach was as I expected it to be. His willingness to listen without making you feel hurried is excellent. When you are with him, he gives the impression that you are his only patient and he has all the time in the world to listen to you and he will always respectfully answer all questions. He has been my doctor for more than 20 years and during my last visit i learned that I was his very first patient.

January 28, 2020 12:11 PM

Dr. Imlach ordered lab work that same day. Although the wait time to see him was short, the wait time for the lab tests was extremely long. I waited more than 3 hours and when after almost everyone else was called and i was finally call the lab tech so very rude, that one of her coworkers call her on her rudeness. All the techs were very unprofessional. Examples: eating in my present, discussing eating habits and dinner plans. There were still a few patients waiting for lab work.

January 28, 2020 8:56 AM

I had my blood work done previous to meeting with Dr. Imlach and he went over my concerns with a calming effect. My fears for my family history of Alzheimer's were discussed in depth and encouragement for my walking a thousand miles last year were acknowledged and praised. Good visit.

January 28, 2020 8:56 AM

I have had Dr. Imlach for years as my physician. I have made sure that Dr. Imlach is in my network when choosing insurance. In this day and age, it is rare to have a physician care so much about a patient. Dr. Imlach goes above and beyond to ensure my questions and medical needs are meet.

January 28, 2020 6:32 AM

Dr. Imlach is always asking about me & family if I did need any help. I said not now. he told me to call him any time I feel I might need some help - His very considered about me & family.
